BEMOVABLE-TOP CONTIIMTUOUS KILN.

Application filed .Tune 9,

To all wzomit may concem:

Be it known that I, THOMAS B. MoATs, a citizen of the United States,residing at Bucyrus, in the County of Crawford and State of Ohio, haveinvented a new and useful Removable-Top Continuous Kiln, of which thefollowing is a specification.

This invention relates to kilns, the primary object of the inventionbeing to provide a kiln having a removable top or crown whereby the kilnmay be emptied or filled from a point exteriorly thereof.

A further object of the invention is to provide a Crown Constructed of aplu'rality of interloc-king blocks for'med of fire clay or the like.

Tith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in thepreciseembodiment of the invention herein disclosed, may be made withinthe scope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawingsz- Figure 1 is a transverse section-al Vviewthrough a kiln Constructed in accordance with the present invention.

1Figure 2 is a fragmental plan view of the ki n. v

Figure 3 is a fragmental side elevational view of the kiln.

Figure 4 is an enlarged detail view disclosing the means for connectingthe frame work of the crown, to the fire clay bricks.

Referring to the drawings in detail, the kiln is of the usualconstruction as far as the base or body portion thereof is concerned,and is shown as provided with the usual fireboxes 5 which communicatewith the smoke stacks through the ducts 6 and passageways 7.

Heat is direoted to the interior of the kiln in the usual manner,through the passag'eways 8 dis'posed in the opposite sides of the kilnand formed in the side walls 9 thereof.

The upper inner surfaces of the walls 9 of the kiln are inclined as at10 to conform to the inclined surfaces 11 of the crown 12,

so that When the crown is positioned on the sicle walls 9, the inc'linededges of the Crown 12 will contact with the inclined edges lO causingthe crown to be properly seated on the kiln walls in a manner to preventlateral movement thereof.

The crown 12 which forms an important feature of the invention, isformed of a plurality of curved supporting beams 13 which have rightangled extremities adapted to rest on the upper edges of the side walls9 of the kiln. The supporting beams 13 are arranged in spaced relationwith each other throughout the length of the kiln, and have connectionwith the longitudinally disposed eye beams let which are supported inspaced relation transversely of the crown 12.

These I beams 14 provide supports for the fire clay blocks 15, each ofwhich being provided with a groove of a shape to conform to the contour-of an I beam, so that the fire clay blocks may be positioned on the Ibeam.

Each block 15 is provided with a lateral groove 16 formed in one sideface thereof,

there being provided a tongue 17 extending from the opposite side facethereof, the tongue 17 being designed to fit within the groove 16 of theadjacent block 15, when the blocks are positioned on the I beams of theCrown.

The blocks 15 are also formed with reinforcing walls 18 which connectthe side walls of the blocks, strengthening the side walls of the blocksand rendering the same capable of withstanding the strain direct-cdthereto by the weight of the adjacent block.

From the foregoing it will be seen that a crown constructed inaccordance with the present invention, may be readily and easily removedby connecting a crane thereto, it being understood that the top is to beremoved in sections, the crane having connection with the sections inany suitable manner whereupon the oven may be readily lilled from thetop thereof.

Then the oven has been filled, it is obvious that the c-rane may beoperated to return the crown to its normal position.

Having thus described the invention, what is claimed as new is A kilnincluding side walls having the upper inner surfaces thereof inclined, a

crown comprsng curved supporting beams, I beams having connection withthe curvecl supporting beams, a plurality of blocks having grooves toaccommodate the I' beams, to support4 the block, and said blocks havinglateral tongues and grooves, Whereby advjacent blocks may beinterlocked-` THOMAS' B.
